Monday night I was fortunate enough to attend the kick-off party for the brand new The Lord of the Rings: The Motion Picture Trilogy Extended Edition Blu-ray at West LA's Best Buy store. Attendees, many of them in costume, were greeted by a special appearance by Rings and Fringe star John Noble, who signed the new box set for the first one hundred and fifty fans in line. And because I love you guys so much, I made sure to ask Noble about the upcoming fourth season of Fringe – as well as about the interesting similarities between his Rings character Denethor and his character on Fringe, Walter Bishop. Find out what Noble had to tell me after the jump.

Right now it seems there are similarities between Denethor and Walter – they've both lost a son and their sanity is sometimes more than a little shaky. If Walter were to give Denethor some advice, what would it be?"Just chill out, man!" [Laughs.] I don't know… There are similarities in the sense that you've got two very proud and powerful men gutted, and having to respond to being gutted. We saw Denethor respond in a certain way. We'll see how the other fellow responds. This'll be a season for discovery.

Anna Torv mentioned to me the other night that she'd like to see how Olivia functions, at least for a little while, without Peter in her life, and to see how that plays out. Is that something you're also curious about for Walter?Oh yeah. See, the thing that rescued Walter, once they pulled him out, the thing that humanized him, was Peter. Finding this relationship with his son, that brought Walter back into the human race. Now if he doesn't have that, if he doesn't have any love in his life, what's going to happen? He's been in an asylum without love in his life all this time, if he's working without love in his life… I hope they give him Jean at least – Jean the cow! No, I am seriously thinking about that, because I know for a while I'm going to have to work on that loveless Walter. And I'm stewing around in my head already. [Laughs.]

Is it possible the grandchild he might have could fill that void in his life?Well, it depends. If there's no Peter then there's no child. It's an interesting point.

Would you like to see new universes on the show, beyond those we've seen already? We know there are two universes, and we actually know this from science. Science will tell us that there are multiple universes. I think that there's a possibility, probably not this season, but… I know that some of the audience is saying "The thing that will save the two universes now is an external threat. That's what brings people together." I've heard this from fans and I think it's very clever. So if these two universes have to meet, what's gonna make them do it? Suddenly, if there's an external threat… I've got my fingers crossed that that'll happen.Source:fearnet.com
